Throughout history, herbs and spices have been extremely popular, used as medicines and aphrodisiacs as well as making their way into dinner. A plant that the Romans (and ancient Greeks and Egyptians) would have been familiar with was Silphium. They thought it was the finest of all seasonings, as well as a top notch medicinal plant. The Romans got a taste for meat from animals fed on Silphium, and it seems that the herb may well then have been grazed into extinction. It never seemed to make it into cultivation. Another possible explanation of Silphium’s disappearance is that a change in the Mediterranean climate meant it could no longer thrive, and died out naturally. According to Pliny, the last known Silphium plant was given to Emperor Nero as a gift.
